Emission factor from UOS v7.0.1

Refrigerants - R-410A

Iceland · Fugitive releases · Any year

Each kilogram of R-410A released to the air counts as 1,924 kg CO₂e, its 100-year warming potential under IPCC AR5. UOS gives one figure, for use in any year.

One value, for any year

UOS sets no date window, so there is no year to pick.

Reference year 2024

1 kg leaked = 1,924 kg CO₂e

The same warming over 100 years as releasing 1,924 kg of carbon dioxide.

Refrigerant you topped up this year

1 kg= 1,924 kg CO₂e

No top-up records? Charge × yearly leak rate gives the kilograms.

Where 1,924 comes from

Published as one number

UOS prints this factor as a single figure, with no parts to add up and no split by gas.

Reporting this kilogram under the GHG Protocol

Scope 1 1,924

Gas that escapes from equipment you run is a direct emission, so it is your Scope 1.

Every horizon, every IPCC report

A warming potential rests on two choices: how many years of warming are counted, and which IPCC assessment report supplies the numbers. UOS publishes one of these 9 cells; the other 8 read “Not published by UOS”.

What this number covers

One step: refrigerant leaving your equipment. Your records give the kilograms; the factor converts them.

  1. Refrigerant in your equipment

    The charge in a heat pump, air-conditioning unit or chiller. No emission while it stays in the circuit.

    Starting point, not counted

  2. Leak to air

    Refrigerant lost through seals and joints, during servicing, or in a failure. Counted as the kilograms you top up.

    Included1 kg

  3. Warming over 100 years

    Heat trapped by that kilogram, compared with 1 kg of CO₂: its GWP100 from the IPCC's fifth report.

    Included× 1,924

  4. Your footprint

    1 kg leaked, reported as CO₂e.

    = 1,924

Outside this boundary

  • Making the refrigerant
  • Recovery at end of life
  • Power the unit uses

Buying the gas is Scope 3, category 1, with its own factor, not this one.

A warming potential, not a measurement

Nobody measured this number at a site. It is the warming caused by 1 kg of the gas over 100 years, divided by the warming of 1 kg of CO₂. It is the same wherever the leak happens.

kg leaked × 1,924 = kg CO₂e
